Interactive External Hooks

[Kelsey Farenholtz]

I would like to add a hook that warns the user when they are pushing a binary encoded file.  I do not want to block the push explicitly, but would like to prompt the user (via the command line) that they are checking in a binary file, and allow them to interactively allow or disallow the commit via the prompt.  The documentation said there were examples on giving the user output, but was wondering if there was an example for prompting the user for information as well, or if this is even allowed with this plugin?

Thanks for your help!  Also, great plugin!

No, there is no way to read data from user, because it's not allowed by specification of git push protocol/git push command implementation.

However, you can implement simple countdown and slightly suspend push process with notifying user that he is just about of pushing binary blob.

I've done it for checking coding standards.

You need to package this as a pre-receive plugin that never rejects commits. The output you want to show to the user has to go to hookResponse.out().

Thanks! I'll look into both of these methods.
